A pool has a length that is 3 times the width. Write the algebra radical value of the corner to corner distance
Answer:
The distance between corner to corner is equal to √10 times the width.
D = √10*W
Step-by-step explanation:
For a rectangle of length L and width W, the distance between two opposite corners can be calculated if we use the Pythagorean's theorem, where we can think on the length as one cathetus, the width as another cathetus and the diagonal as the hypotenuse.
Then the length of the diagonal is:
D^2 = L^2 + W^2
D = √( L^2 + W^2)
In this case we know that the length is 3 times the width, then:
L = 3*W
Replacing this in the equation for the diagonal we have:
D = √( (3*W)^2 + W^2) = √( 9*W^2 + W^2)
D = √( 10*W^2) = √10*√W^2 = √10*W
D = √10*W
The distance between corner to corner is equal to √10 times the width.
Find the area of the shaded region.
Answer:
area = 3.44 in²
Step-by-step explanation:
area of square = 4 x 4 = 16 cm²
area of circle = (3.14)(2²) = 12.56 cm²
area = 16 - 12.56 = 3.44 in²
Find the unit rate for each, then compare. Which is faster?
8 laps in 70 seconds
12 laps in 98 seconds.
Answer:
8 laps in 70 seconds is faster.
Step-by-step explanation:
If we divide 70/8 and 98/12 we get the following:
70/8= 8.75
98/12=8.16
8.75>8.16
The unit rate is 1 lap in 8.75 seconds and 1 lap in 8.16 seconds
Verify the equation: (sin x + cos x)(tan x + cot x) = sec x csc x
Answer:
The equation (sin(x) + cos(x))(tan(x) + cot(x)) = sec(x)csc(x) is not solvable because the two sides are not equal.

how many sides a hetergon got
Answer:
6
Step-by-step explanation:
answer:
so there isnt such thing as a hertergon but if your looking for how much sides does a heptagon have
the answer is 7 !
ill add a photo here for you to see just in case i got the shape you were looking for wrong
but there isnt really any way to see how much sides a shape does have, the easiest way is to count the sides!
hope this help you and your problem! if you need anything else or if i didn't explain it well enough then please ask! hope you have a good rest of your day :)
sorry this is probably easy but i need help
Answer:
Step-by-step explanation:
there is 1,000 total students... so divide 360 / 1000
so you have 0.36 for each student... then multiply by the freshmen,
.36 * 300 = 108 :)
how am i supposed to solve this ?
Answer:
Step-by-step explanation: so first you got to distribute the on both sides so like the 2 and the ten from there you just eliminate and do it like normal. I’m sorry I’m bad at at explaining it but I hoped it helped some how :)
A property worth 10,480.00 is shared between Eugenia and her 10 brothers in ratio: 1:4 respectively.The 10 brothers shared their portion equally.Find each the brothers share.
Answer:
838.4
Step-by-step explanation:
From the question,
Total worth of the property = 10480.
Eugenia share: Her 10 brothers share = 1:4
Total ratio = 1+4 = 5.
Her 10 brother's share = (4/5)(10480)
Her 10 brother's share = 41920/5
Her 10 brother's share = 8384.
If the 10 brothers shared their portion equally,
Each brother's share = 8384/10
Each brother's share = 838.4

Sarah is self-publishing her 300-page novel and wants to estimate the printing costs.
Answer the questions to estimate the cost of printing a 300-page paperback book.
1. What is the y-intercept for the trend line? What is the real-world meaning of this point?
2. One point on the trend line is (200, 6). Using this point and the y-intercept, find the slope of the trend line. Show your work.
3. What is the real-world meaning.of the slope?
4. Use the slope and y-intercept to write an equation for the trend line in slope-intercept form.
5. Use your equation to estimate the cost of printing Sarah's 300-page book.
1. Y-intercept b=5
That means it has a 5.00 starting fee.
2. Using the formula (Y2-Y1)/(X2-X1) we will find the slope between the two points.
Point one (X1 and Y1) will be the Y-intercept.
X1,Y1 = (0, 5.00)
Point 2 (X2 and Y2) will be the point on the trend line.
X2, Y2 = (200, 6.00)
Plug in:
(6.00 - 5.00)/(200 - 0) = 00.5 or 1/200.
3. When printing 200 pages each page will cost $.005.
4. .005x+5
5. .005x+5
.005(300)+5=6.5
good luck♡♡!!

What is the line of symmetry for the parabola whose equation is y = x2 + 10x + 25?
A-x = -5
B-x = 5
C-x = -10
Answer:
x = -5
Step-by-step explanation:
Please write this as y = x^2 + 10x + 25. Here the coefficients are {1, 10, 25}.
The equation of the axis of symmetry is x = -b/[2a], which here is
x = -10 / [2*1] = -5

A rectangle’s length is three times its width, w. Its area is 243 square units. Which equation can be used to find the width of the rectangle?
a. w2 = 3(243)
b. 3w2 = 243
c. 4w2 = 243
d. 3w2 = 3(243)
please im on a timed test
Answer:
b) 3w² = 243
Step-by-step explanation:
area = L x w
L = 3w
substitute for L:
243 = 3w x w = 3w²
3w² = 243

When rolling a die why is the probability of rolling a 2 or 3
Answer:
1/3
Step-by-step explanation:
If you're talking about a 6-sided die, then there are 6 sides. Rolling a 2 or a 3 would be a 2/6 chance. To simplify if from there, you can also say that there is a 1/3 chance.

Jaden is playing hide-and-seek with Henry and Valentina. Henry is hiding 12 meters south of
Jaden, and Valentina is hiding due east of Henry. If Jaden is 20 meters from Valentina, how many meters far apart are Henry and Valentina?
Answer:
Henry and Valencia are 16 m apart.
Step-by-step explanation:
A sketch to this question shows that their distance apart forms a right angled triangle. So then, we can apply the Pythagoras theorem.
Let the distance between Henry and Valencia be represented by x, so that;
[tex]/hyp/^{2}[/tex] = [tex]/adj 1/^{2}[/tex] + [tex]/adj 2/^{2}[/tex]
[tex]20^{2}[/tex] = [tex]x^{2}[/tex] + [tex]12^{2}[/tex]
400 = [tex]x^{2}[/tex] + 144
[tex]x^{2}[/tex] = 400 - 144
= 256
x = [tex]\sqrt{256}[/tex]
= 16
x = 16 m
Therefore, Henry and Valentia are 16 meters apart.
